Mesh current collector for dry electrode lamination

A method for manufacturing electrodes for a battery cell, comprising:

• providing a first free-standing electrode;
• providing a second free-standing electrode;
• providing a current collector including holes, wherein the current collector is selected from a group consisting of a wire mesh, an expanded metal sheet and a perforated metal sheet;
• coating the current collector with a binder coating without using a solvent;
• and
• laminating the current collector coated with the binder coating to the first free-standing electrode and the second free-standing electrode using at least one of heat and pressure without using a solvent,
• wherein the first free-standing electrode is formed with a power mixture that comprises an active material that exchanges lithium ions and a binder selected from a group consisting of polytetrafluoroethylene (PTFE) binder and a thermoplastic polymer binder,
• wherein the power mixture is pressed and calendared to form the first free-standing electrode without a solvent,
• wherein the first free-standing electrode is a dry electrode, and
• wherein the holes enable physical contact between the first free-standing electrode and the second free-standing electrode during the laminating such that the laminating results in electrode to current collector adhesions between the first free-standing electrode and the current collector and between the second free-standing electrode and the current collector in addition to electrode to electrode cohesion between the first free-standing electrode and the second free-standing electrode.
